Product Overview

Watergate ARS

Watergate ARS is a revolutionary yet simple stormwater product. It is an automatic retractable screen that blocks trash and debris from entering storm drains during dry weather flows and light to moderate rain. During these periods the screen remains closed and locked to allow removal of trash and debris by routine street sweeping operations. The Watergate features a patented front-pivot design to bias the screen toward the closed position and provides more effective closing and locking. The positive closing force vastly reduces the possibility of debris becoming trapped under the screen and preventing it from fully closing and becoming locked.

Sizing Table

Operation

Stormwater flows of approximately 2-inches or more will unlock and open the Watergate. During these periods of increased flow and heavy rain, the screen unlocks to allow runoff into the storm drain to prevent flooding. When the water flow subsides, the screen will return to the closed and locked position. Patented Positive Force Closing reduces the possibility of debris becoming trapped under the screen. The Integral Control Arm prevents opening beyond operational limits. If the screen is clogged with debris, the top overflow design directs flow onto the actuator, which helps the unit open.

Closed & Locked Position

During dry weather flows and ligth to moderate rain, the Watergate, prevents trash and debris from entering the catch basin. This allows routine street sweeper maintenance to address trash before it enters the storm drain system.

Open & Unlocked During Increased Flow

During heavy rain events, increased water flows will unlock the Watergate’s screen, allowing it to open only as far as necessary to allow runoff to enter the catch basin and prevent flooding while still blocking larger trash and debris. This patented design intelligently prevents clogging and flooding issues often found with fixed screen systems. After any storm event, the screen will return to the closed and locked position automatically.

Performance

The Watergate ARS stormwater system is a partial capture, first flush device. The California Regional Water Quality Control Board has recommended the Watergate ARS to be placed on the face of the catch basin openings to keep large trash particulates from entering a catch basin.

Maintenance & Installation

Routine street sweeping is the only maintenance necessary.

Routine street sweeping is the only maintenance necessary. The Watergate will remain closed and locked during routine street sweeping and is not affected by the sweeping brushes. For added peace of mind, when large storms are expected, the Watergate can be manually locked open from the street by hand using receptors in the control arms.
